What is the role of multi in redis? I believe many inexperienced people don't know what to do about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The summary is as follows

Pipeline selects client buffering, multi selects server buffering

Due to the inconsistent number of requests, multi needs to send each command to the server once, and pipeline sends it to the server at last. The number of requests is reduced compared with multi.

Multi/exec can guarantee atomicity, while pipeline does not guarantee atomicity (the atomicity of redis is not equal to the atomicity of database)

If redis, after the transaction is started, the command queue can know that this is a problematic command during inspection, then atomicity can be guaranteed at this time.

If you have to wait until run time to determine that the command is unexecutable, the redis skips the command and executes the following command. Remember! Remember!

After reading the above, have you mastered the role of multi in redis? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
